Abstract
The solid-state structure of a tetranuclear mixed-metal cluster (C5Me5)WOs3-(CO)12H (2b) which has hydride ligant bridging across a WOs bond is presented. In solution, the isomer adopting the solid-state structure is in equilibrium with a second isomer (2a) in which the hydride is associated with an OsOs edge. Complex 2 crystallizes in the orthorhombic space group Pna21 with a 21.598(6), b 8.973(4), c 14.121(4) Å, Z = 4; 2260 observed reflections with I > 3σI were used in the refinement. The R values converged to RF = 0.023, Rw = 0.018 and GOF = 1.500. © 1989.
